Asrock B650M PRO RS Wifi EXPO problems-"solve"

For everyone who have big issue with expo, like Bsods, no boot after apply expo etc. I had same issue with my RAM kit that is not in QVL list for this MB, and nothing was working to make my ram kit(4800) working on 6000, I was fighting with OC my memory useing EXPO profiles, but without a reslut for 2days, and only get no boot at all, so I tried to manualy OC my RAM kit without EXPO, so expo is "disabled", and...this was a solution! Right now I have my memory set exactly the same settings like in EXPO profile(Mhz, Voltage, timings) I set all manualy, plus extra set Infinity fabric to 2000MHz, set Soc Voltage to 1.2V, spread spectrum disabled, Gear down mode Enable, set first 4 timings same like in EXPO profile, all other timings are on auto, PC boots up 30-60s. after exiting BIOS after saveing settings so be patien, after reboot from widnows boot times is almost instantly ;) If someone will whant more info, pls write, than I will make some photos from bios, I changed some more settigns in bios...one from ram but i don remeber name of this options right now. My memory: Viper Venom 6000 CL30 ;) PS. all issue coulde be in one timing set in EXPO profile(Im not ram specialist I only assume), in my case I think with tWR, so in EXPO tWR is set to 91 in 6000 mode, but when I was trying to set it manualy to 91, bios automaticly change this to 90, there was no way to set it like exactly like in expo profile :/ but RAM is working stable on almost all setting it mean to be ;)

I will try make screens today but I dont promise, moste important is to, set manualy Ram voltage, Mhz, and first 5 timings for you ram kit like it is in expo profile, and disable Spread spectrum, also you can change Infinity fabric to 2000Mhz and set Soc Voltage to 1.225-1.25V and thats it, all should work fine, first boot after saveing this settings in bios can be in 30-60sec.
